With barbell on rack at chest height, position the bar so that it’s on the front of your shoulders. With arms crossing place hands on bar, keeping elbows facing straight forward. The bar should be resting upon the top of your shoulders. Unrack the bar and position your feet shoulder width apart. Keeping chest up and elbows straight, squat down making sure to put weight towards the back of your feet. Descend until thighs are parallel to the ground and return back to the starting position.
